George Chen, 19, and Weihan Wang and Chen Yuang Hong, both 20, all died from multiple stab wounds in his flat.

Wang and Hong, who were his room-mates, had planned to move out, telling pals Rodger was “too weird”. The student had vowed in his manifesto: “The first people I would have to kill are my two housemates to secure the entire apartment for myself as my personal torture and killing chamber.

“I will torture some of the good-looking people before I kill them, assuming that the good-looking ones had the best sex lives.

“All of that pleasure they had in life I will punish by bringing them pain and suffering.’’

The second phase of his plan was to launch a “war on women” who had rejected him and left him a frustrated third-year college virgin. He climbed into his BMW and drove to a sorority house where he shot dead Katherine Cooper, 22, and Veronika Weiss, 19.

Then he got back in his car and drove to a nearby deli where he shot dead bystander Chris Michael-Martinez, 20, in an attack captured on CCTV.

After mowing down two cyclists Rodger shot himself dead as armed police closed in on his crashed car.
